I think we are all agreed
The question is conformance, and the test suite that decides conformance.
What defines a cert as conforming is what we can address in the spec. We
cannot address the infinite number of variations imposed by relying party
policy. Personally, finding out what 10 research sites think is good policy
is irrelevant to me. It's just more web crud.
Now, is Hans original cert conforming - or NOT? (the one generated with
some critical extensions)
Yes, say I. The conformance suite should be granting him access to the
conformance test target.
If folks accept this, then folks need to configure that Apace mode to ignore
v3 criticality, for that installation to be in "conforming mode". As it
stands, the site that Hans accessed is in non-conforming mode (for webid
purposes). Im guessing Joe indicated how to fiddle Apache config so it
approximates webid conforming mode.
What we do not do ... is require Hans to have 2 certs now. Certs in webid
land are not fussy. He can use any he likes, without having a special burden
due to webid. This is because non of the extensions have any significance
(aside from the SAN URI) - because conforming systems will not even verify
the cert signature, or reject a cert with a unknown/broken signature.

Excellent summary, Henry - I'm with you on pretty much every point.
As an adjunct: I'm envisaging systems built on/leveraging WebID which may
well take advantage of other facets of X509 which WebID itself doesn't
necessarily care about - so I'm reticent to "throw the baby out with the
bathwater", as it were.
